The car is not yet running, however some progress has been made.
Replaced the exhaust camshaft with some help from my coworkers, during that the rear camshaft half moons and rocker cover gaskets. Forgot to order front camshaft seals before, done that for now. Every rubber hose or gasket is just rock hard, need to get these fixed in the future for new ones as well.
However, the main reason why everything went wrong in October was the bracket for the CAS. It has a crack in it, how that has developed I am not sure and at this point it does not matter anyway. Due to the crack, the bracket is slightly warped. Which changed the position of the CAS and hence the camshaft half key was broken. Need to find a new one and then hopefully can get everything running, will be checking timing marks just incase.
And here's a little picture of the car waiting for future work, looks incredibly small next to an Escalade.
